### Please describe the problem.

Release 10.20230214 was supposed to give the ability to refresh the view branch with `sync` to
reflect any changes made to metadata or parent branch, yet for users of crippled filesystems
(for whom the view branches are a bit marginal anyway considering that symbolic or hard links
are not employed) who are dependent on adjusted branches this does not work. It seems git annex
tries to reach for the parent branch in the form of `adjusted/master` but normally it should be
similar to `adjusted/master(unlocked)` with the parenthesized portion at the end.

[[!format sh """
X:\git-annex-tests\annex-view-test-a [views/adjusted/master(unlocked)(subdir_=_)]> git status
On branch views/adjusted/master(unlocked)(subdir_=_)

fatal: not a valid object name: 'adjusted/master'
git-annex: failed to update refs/heads/synced/adjusted/master
"""]]

### What steps will reproduce the problem?

Use a crippled filesystem on Windows with adjusted unlocked branches and enter a view branch
and then try to `git annex sync --no-commit` -- the sync at least partially fails.

### What version of git-annex are you using? On what operating system?

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Git Annex is great. I use it several times a week with my multigigabyte backups, where it gives structure to my image-based backup routines, so you could say I'm a believer. :)

Big thanks, Joey!
